' LOOSE-LEAEBINDER. I

Application filed' January To all whom it may concern: 5

'Be it known that I, HOLLAND D. COTTRELL,

' a citizen of the United States, and'residing at Detroit, in the :county of Wayne and Stateof -Michigan, have invented anew and Improved Loose-Leaf'Binder, of which the following is-a specification. This invention relates to loose a loose leaf binder from which the leaves may be easily removed or replaced.

Another object of the invention lsto prov vide a loose leaf binder which will fold compactly and willltakeup less storage space than the ordinary types of loose leaf binders. I

Anotherobject of the invention is to provide a loose leaf binderin which the binding mechanism may be readily unlocked to allow insertion of new leaves and may be quickly'locked again to hold the leaves in place. A further object of the. inventionis to provide a loose leaf binder of the character described which is composed of few parts which are of low,cost thus producing an 1 1 leafibinder embodying my invention.

efii'cient binder at a very low prlce. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects areattained is-shown in the accompanying drawings in which I V i Fig. .1 1s a perspectlve V16W' of. a loose Fig. 2 is a longitudinal section there through,

are glued thereto at the points 6. A fabric strip 14 is pasted over the folded edge of the binder and secures the ends of the strips 4 and 5 securely to the outer cover of the leaf binders v i and the object of the invention is to provide is, 1925. Serial No. 3,285.

binder. The opposite ends of the fabric straps 4 and 5 are secured beneath the inturned flap 7 of'the-cover .1 by the clips,8 which extend through the cover 1, flap 7 and straps 4 and 5 as shown more particularly in F igs.;2 and5.- The st-raps-4-and 5 extend through apertures lfi provided therefor in a cardboard ;shee,t 9 and this cardboard sheet 9 normally lays over. the straps 4 and 5 I and is provided with an'extensionlO which engages beneath. theflap 7 between the straps 4 and 5'as shown in Fig. 5. This cardboard sheet 9, is; provided with an aperturell into which the finger may be inserted fordisengaging the cardboard sheet 9 from beneath the flap 7. The cardboard sheet 9normally lays flat against theinside of .the cover l when the portion 10 thereof is engaged be: neath the flap 7.. The paper sheets are providedwith notches 12* as shown in Fig. 7, to receive the straps 4and 5, there being a plurality of :paper sheets held in the binder in, this manner. ,Atthis time the binder may be opened as shown in Fig. 3without loosening. the paper sheets from the binder. To unlock the binding device. andallow removal ofthe paper sheets the finger is inserted in the aperture 11 and;the portion 10 is disengaged from beneath the flap 7 at whichtime the cardboard sheet 9 may; be moved to the position shown in Fig. 4thus allowing the paper sheetsto come out ofthe fold. of the: binder at which time the sheets may be removed from the straps 4 and 5 r or new. sheets maybeplaced thereon; At

this time the binder may be folded shut and the cardboard-fsheett) moved back to the I position shown in Figs. 2land 5 which moves the sheets back to the 1 former position. in the foldof the binder and locks them in placeas shown in Fig. 2. Itwill'thus be seen that the sheetsmay be easily removed from or replacedin the binderand'wlien locked in thebinder cannot be withdrawn without first disengaging the cardboard sheet 9. This device is very cheap to manufacture and having no extensions on the sides the binders may be stacked in a small amount of space.

From the foregoing-description it becomes evident that the device is very simple and efficient in operation, will not easily get out of order, is composed offew parts and is of consequent low manufacturing cost and provides a device which accomplishes the ob-' ects described.

H to the front cover member adjacent the hinge, a series of paper sheets notched to fit over the straps, a semi-flexible cardboard retaining member having apertures at one edge through which the straps extend and being slidable on the straps to bindingly engage the sheets between the retainer member and the front cover member, a tongue on one edge of the retaining member engaging beneath the flap between the straps to hold the retaining member in the binding position, the retaining member being of the same shape as the back cover member and being provided with an aperture by means of which the retaining member may be grasped for disengaging the tongue of the retaining member from beneath the flap.

2. A loose leaf binder comprising a back and a front cover member hinged together, the back cover member being provided with an inturned flap at the outer edge, a pair of straps secured at one end between the back cover member and the flap and being secured at the opposite end to the front cover member adjacent the hinge, a series of paper sheets notched to fit over the straps, a semi-flexible retaining member slidable on the straps to bindingly engage the sheets between the retaining member and the front cover member, and a tongue onrthe retaining member engaging beneath the flap between the straps to hold the retaining member in the binding position.

3. A loose leaf binder comprising a back and a front cover member of flexible material hinged together, a pair of strapssec'ured to the outer edge of the back cover member at one end and secured at the opposite end to the front cover member adjacent the hinge, a series of paper sheets notched to fit over the straps, a retaining member of flexible material through which the straps extend, the retaining member being slidable on the straps to bindingly engage the sheets a between the retaining member and the front end and secured at the opposite end to the front cover member adjacent the hinge, a series of sheets notched to fit over the straps, a retaining member slidable on the straps to bindingly engage the sheets between the retaining member and the front cover member, and a tongue on the retaining member engaging beneath the said flap to hold the retaining member in the binding position.

5. A loose leaf binder comprising a back and a front cover member hinged together, a pair of straps secured to the outer edge of the back cover member at one end and secured at the opposite end to the front cover member adjacent the hinge, a series of paper sheets notched to fit over the straps, and a retaining member slidable on the straps to bindingly engage the sheets between the retaining member and the front cover member, an inturned flap on' the back cover member, and a tongue on the retaining member adapted to engage beneath the inturned flap to hold the retaining member in binding position.

6. A loose leaf binder comprising a back and a front cover member hinged together, a pair of straps secured to the outer edge of the back cover member at. one end and secured at the opposite end to the front cover member adjacent the hinge, a series of paper sheets notched to fit over the straps, a retaining member slidable on the straps to bindingly engage the sheets between the retaining member and the front cover'memher, and means for securing the retaining member in binding position.

In testimony whereof I sign this specification.
